First, what is chronic sinusitis and how is it different from acute sinusitis?
Common symptoms of both acute and chronic sinusitis can include fatigue or weakness, general malaise, low-grade fever, pressure in the face (including cheeks, jaw, teeth, behind the eyes or forehead), headache, sore throat, postnasal drip, cough, congestion, loss of smell or bad breath.
Acute sinusitis is a sudden onset of inflammation in the sinuses that typically lasts for less than 4 weeks, and often starts with a viral or bacterial infection. Early treatment of acute sinusitis usually involves a variety of treatment options including nasal irrigation (rinsing sinuses with a saline solution), decongestants, pain relievers, steroid nasal sprays, antihistamines and/or antibiotics. If your sinusitis symptoms are not sufficiently resolved with early treatment options, and your symptoms persist for at least 3 months, you may be experiencing chronic sinusitis.
Chronic sinusitis is a long-term inflammation of the sinuses that lasts for at least 3 months. It is often referred to as Chronic Rhinosinusitis (CRS) because it is accompanied by nasal airway inflammation and often begins with rhinitis symptoms. Chronic Rhinosinusitis is one of the most common chronic diseases in the US, and affects people of all ages.
